Description

Technical Field

[0001] This utility model relates to the field of rope winders, and in particular to a rope winder mechanism with tension adjustment function. Background Technology

[0002] A rope winder mechanism is a mechanical device used to neatly and evenly wind steel cables, ropes, or other similar objects onto a drum or reel.

[0003] When using the rope winder mechanism, the steel cable is wound around the surface of the first and second drums of the support frame. Bolts and nuts are installed on one side of the second drum. The nut moves on the bolt to adjust the state of the compression spring. The compression spring forces sufficient support between the second and first drums for tension adjustment, further increasing the friction between the wire rope and the pulley. However, since there is no lubricating oil on the surface of the steel cable during use, prolonged friction between the cable and the first and second drums causes damage, affecting their service life and consequently impacting the lifespan of the rope winder mechanism. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when the first and second drums are in use, there is no lubricating oil on the surface of the steel cable. After the steel cable rubs against the first and second drums for a long time, damage is caused to the steel cable and the first and second drums, affecting their service life and thus affecting the service life of the rope winding mechanism.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rope winder mechanism with tension adjustment function, including a bracket, a first drum on one side of the bracket, a second drum inside the bracket, a bolt on one side of the second drum, a nut on one side of the bolt, a compression spring on the side of the bracket and the nut close to each other, and the compression spring is sleeved on the surface of the bolt, and a lubrication device on one side of the bracket, the lubrication device lubricates the steel cable, the first drum and the second drum.

[0006] The effect achieved by the above components is as follows: When the rope winding mechanism is used, the steel cable is wound around the surface of the first and second drums of the support. Then, a bolt and nut are set on one side of the second drum. The nut moves on the bolt to adjust the state of the compression spring. The tighter the compression spring is compressed, the greater the reset force will be, so that the compression spring has a sufficiently large supporting force. Then, through the compression spring, a sufficiently large supporting force is forced between the second drum and the first drum to perform belt tension adjustment, further increasing the friction between the wire rope and the pulley.

[0007] Preferably, the grooves on the surfaces of the second roll and the first roll are both U-shaped grooves.

[0008] The effect achieved by the above components is as follows: by opening several U-shaped grooves on the surfaces of the second drum and the first drum, the contact area between the second drum and the first drum and the steel cable is increased, thereby increasing their friction and enabling the second drum and the first drum to better drive the steel cable to move.

[0009] Preferably, the lubrication device includes a fixing screw, a storage box, a box cover, an electric telescopic rod, a piston, and a connecting pipe. The fixing screw is inserted into one side of the storage box to fix it to the bracket. The box cover is located on one side of the storage box to seal the entrance of the storage box. The electric telescopic rod is located on one side of the storage box. The piston is located at the output end of the electric telescopic rod and inside the storage box. Several oil outlet holes are opened on one side of the connecting pipe, and a solenoid valve is installed inside the connecting pipe.

[0010] The aforementioned components achieve the following effect: When using the lubrication device, the storage box can be placed on one side of the bracket, and then the fixing screw can be turned to allow the screw to pass through one side of the storage box and be threaded into the bracket. The storage box is then fixed to one side of the bracket, with the connecting pipe near the oil outlet contacting the steel cable. The box cover is then rotated open to add lubricating oil into the storage box. The cover is then re-threaded and secured. The electric telescopic rod fixed to one side of the storage box is then activated, causing the piston fixed to the output end of the electric telescopic rod to move inside the storage box. At this time, the solenoid valve inside the connecting pipe is opened, allowing the lubricating oil inside the storage box to flow. The lubricating oil is squeezed to reach the inside of the fixed connecting pipe on one side of the storage box, and then discharged through the oil outlet on the side of the connecting pipe. The surface of the steel cable passing through the connecting pipe will then be coated with lubricating oil, thus completing the lubrication. The lubricating oil on the steel cable will then reach the surface of the first and second drums. By using a lubrication device, lubricating oil can be added to the steel cable, and when the steel cable moves, the lubricating oil is carried to the surface of the first and second drums, thus completing the lubrication of the steel cable and the first and second drums, thereby improving the service life of the steel cable and the first and second drums, and thus improving the service life of the rope winder mechanism.

[0011] Preferably, the oil outlet holes of the connecting pipe are arranged circumferentially at equal intervals on the side near the steel cable.

[0012] The effect achieved by the above components is as follows: after the lubricating oil reaches the oil outlet on one side of the connecting pipe, the steel cable blocks the oil outlet, so that the lubricating oil can fill the entire internal space of the connecting pipe. Then the lubricating oil can be discharged from multiple oil outlets at the same time, so that the steel cable is lubricated more quickly.

[0013] Preferably, a support frame is provided on one side of the storage box, and one side of the support frame is connected to a connecting pipe.

[0014] The aforementioned components achieve the following effect: by fixing the support frame to the storage box and connecting pipe, and then supporting the connecting pipe, the connecting pipe can be used more stably.

[0015] Preferably, one side of the lid is provided with several anti-slip blocks to increase the friction on one side of the lid.

[0016] The effect achieved by the above components is to increase the friction on one side of the lid by fixing several anti-slip blocks, making the lid easier to rotate.

[0017] Preferably, a washer is provided on the side of the fixing screw near the storage box to increase the contact area between the fixing screw and the storage box.

[0018] The effect achieved by the above components is that by using a washer between the fixing screw and the storage box, the contact area between the two is increased, thereby improving the fixing effect of the fixing screw on the storage box.

[0019] Preferably, one side of the electric telescopic rod is provided with a reinforcing plate, and one side of the reinforcing plate is connected to the storage box.

[0020] The effect achieved by the above components is to improve the connection strength between the electric telescopic rod and the storage box by fixing the two ends of the reinforcing plate to the electric telescopic rod and the storage box, and to prevent deformation of the connection between the two under stress.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a lubrication device, lubricating oil can be added to the steel cable. When the steel cable moves, the lubricating oil is carried to the surfaces of the first and second drums to complete the lubrication of the steel cable and the first and second drums, thereby increasing the service life of the steel cable and the first and second drums, and thus increasing the service life of the rope winder mechanism.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figures 1 to 4 The rope winder mechanism shown includes a support 1, a first drum 2 on one side of the support 1, a second drum 3 inside the support 1, a bolt 4 on one side of the second drum 3, a nut 5 on one side of the bolt 4, a compression spring 6 on the side of the support 1 and the nut 5 close to each other, and the compression spring 6 is sleeved on the surface of the bolt 4. A lubrication device 7 is provided on one side of the support 1, and the lubrication device 7 discharges lubricating oil through an oil outlet 77 on one side of the connecting pipe 76 to lubricate the steel cable, the first drum 2 and the second drum 3. When the rope winder mechanism is in use, the steel cable is wound around the surface of the first drum 2 and the second drum 3 of the support 1. Then, the bolt 4 and the nut 5 are set on one side of the second drum 3. The nut 5 moves threadedly on the bolt 4 to adjust the state of the compression spring 6 that abuts against the support 1 and the nut 5. Then, the force of the compression spring 6 returning to its original position forces a sufficiently large supporting force between the second drum 3 and the first drum 2 to perform tension adjustment, further increasing the friction between the steel cable and the pulley.

[0032] Figures 1 to 4 The grooves on the surfaces of the second drum 3 and the first drum 2 shown are both U-shaped grooves. By creating several U-shaped grooves on the surfaces of the second drum 3 and the first drum 2, the contact area between the second drum 3, the first drum 2, and the steel cable is increased, thereby increasing their friction and enabling the second drum 3 and the first drum 2 to better drive the steel cable.

[0033] Figures 1 to 4The lubrication device 7 shown includes a fixing screw 71, a storage box 72, a box cover 73, an electric telescopic rod 74, a piston 75, and a connecting pipe 76. The fixing screw 71 is inserted into one side of the storage box 72 to fix it to the bracket 1. The box cover 73 is located on one side of the storage box 72 to seal the inlet of the storage box 72. The electric telescopic rod 74 is located on one side of the storage box 72. The piston 75 is located at the output end of the electric telescopic rod 74 and is located inside the storage box 72. Several oil outlet holes 77 are opened on one side of the connecting pipe 76. A solenoid valve is installed inside the connecting pipe 76.

[0034] Figures 1 to 4 When using the lubrication device 7, the storage box 72 can be placed on one side of the bracket 1. Then, the fixing screw 71 is turned so that it passes through one side of the storage box 72 and is threaded into the bracket 1. The storage box 72 is then fixed to one side of the bracket 1, with the side of the connecting pipe 76 near the oil outlet 77 in contact with the steel cable. The box cover 73 is then rotated open to add lubricating oil into the storage box 72. The box cover 73 is then re-threaded and fixed. The electric telescopic rod 74 fixed on one side of the storage box 72 is then activated, causing the piston 75 fixed at the output end of the electric telescopic rod 74 to move inside the storage box 72. At this time, the solenoid valve inside the connecting pipe 76 is opened, and the lubricating oil inside the storage box 72 is then released. The lubricating oil in the storage box 72 is squeezed to reach the inside of the connecting pipe 76 fixed on one side of the storage box 72. Then it is discharged through the oil outlet 77 on the side of the connecting pipe 76. The surface of the steel cable passing through the connecting pipe 76 will then be coated with lubricating oil to complete the lubrication. The lubricating oil on the steel cable will then reach the surface of the first drum 2 and the second drum 3. By using the lubrication device 7, lubricating oil can be added to the steel cable. When the steel cable moves, the lubricating oil is carried to the surface of the first drum 2 and the second drum 3 to complete the lubrication of the steel cable and the first drum 2 and the second drum 3, thereby improving the service life of the steel cable and the first drum 2 and the second drum 3, and thus improving the service life of the rope winder mechanism.

[0035] Figures 1 to 4 The connecting pipe 76 shown has several oil outlet holes 77 arranged equidistantly around its circumference on the side near the steel cable. After the lubricating oil reaches the oil outlet hole 77 on one side of the connecting pipe 76, the steel cable blocks the oil outlet hole 77 so that the lubricating oil can fill the entire internal space of the connecting pipe 76. Then the lubricating oil can be discharged from multiple oil outlet holes 77 together, so that the steel cable is lubricated more quickly.

[0036] Figures 1 to 4The storage box 72 shown has a support frame 78 on one side, which is connected to the connecting pipe 76. The support frame 78 is fixed to the storage box 72 and the connecting pipe 76, thus supporting the connecting pipe 76 and making it more stable for use. The lid 73 has several anti-slip blocks 79 on one side to increase friction. These anti-slip blocks 79 are fixed to one side of the lid 73 to increase friction, making it easier for the lid 73 to rotate.

[0037] Figures 1 to 4 The fixing screw 71 shown has a washer 710 on the side near the storage box 72 to increase the contact area between the fixing screw 71 and the storage box 72. The washer 710 abuts against the fixing screw 71 and the storage box 72, increasing the contact area between them and thus improving the fixing effect of the fixing screw 71 on the storage box 72. A reinforcing plate 711 is provided on one side of the electric telescopic rod 74, and one side of the reinforcing plate 711 is connected to the storage box 72. The reinforcing plate 711 is fixed to both ends of the electric telescopic rod 74 and the storage box 72, increasing the connection strength between the electric telescopic rod 74 and the storage box 72 and preventing deformation at the connection point under stress.

[0038] Working principle: When using the rope winding mechanism, the steel cable is wound on the surface of the first drum 2 and the second drum 3 of the bracket 1. Then, a bolt 4 and a nut 5 are set on one side of the second drum 3. The nut 5 moves on the bolt 4 to adjust the state of the compression spring 6. Then, through the compression spring 6, a sufficiently large supporting force is forced between the second drum 3 and the first drum 2 to perform tension adjustment, further increasing the friction between the wire rope and the pulley. When using the lubrication device 7, the storage box 72 can be placed on one side of the bracket 1. Then, the fixing screw 71 is turned so that it passes through one side of the storage box 72 and is threaded into the bracket 1. The storage box 72 is then fixed to one side of the bracket 1, with the side of the connecting pipe 76 near the oil outlet 77 in contact with the steel cable. The box cover 73 is then rotated open to add lubricating oil into the storage box 72. The box cover 73 is then re-threaded and fixed. The electric telescopic rod 74 fixed on one side of the storage box 72 is then activated, causing the piston 75 fixed at the output end of the electric telescopic rod 74 to move inside the storage box 72. At this time, the solenoid valve inside the connecting pipe 76 is opened, and the lubricating oil inside the storage box 72 is then released. The lubricating oil is squeezed to reach the inside of the connecting pipe 76 fixed on one side of the storage box 72, and then discharged through the oil outlet 77 on one side of the connecting pipe 76. The surface of the steel cable passing through the connecting pipe 76 will then be coated with lubricating oil to complete the lubrication. The lubricating oil on the steel cable will then reach the surface of the first drum 2 and the second drum 3. By using the lubrication device 7, lubricating oil can be added to the steel cable. When the steel cable moves, the lubricating oil is carried to the surface of the first drum 2 and the second drum 3 to complete the lubrication of the steel cable and the first drum 2 and the second drum 3, thereby improving the service life of the steel cable and the first drum 2 and the second drum 3, and thus improving the service life of the rope winder mechanism.
